linux下重新打包签名生成新的app
解包
apktool d zhibo.apk
改完smail之后
打包
apktool b zhibo/
生成签名(我发现安卓9都能装v1的签名,就没去搞v2的签名)
keytool -genkey -alias abc.keystore -keyalg RSA -validity 20000 -keystore abc.keystore
给apk签名
root/Downloads/android-studio/jre/bin/jarsigner -verbose -keystore abc.keystore -signedjar sign_zhibo.apk zhibo.apk abc.keystore
